Hi Vlad,
thanks for your input.
Obviously, the image sets that we are discussing are not ideal. The world just doesn’t always provide perfect conditions.
And its about understanding which setting causes what kind of response.
That this is not always predictable and varies greatly with the image set is clear (at least to me).
Nevertheless there are people who haven’t grasped all of it (including myself).
So what you said about 10 features being enough for a perfect image set is quite helpful in some way. On the other hand, it doesn’t help with solving something difficult.
I just had a really bad project, a building with lots of vegetation around it (which I could not remove). So there I was with a certain budget having to make the best of it. In my case, rising the Preselector Features from 10 to 20k did the trick. I finally got components big enough to work with. Adding more than 100 CPs was still a lot of work, but I got a useful result in the end, with all 20 GCPs having an error below 5mm. I can live with that.
@Tom:
Sorry, you are right - Preselector is of course for the next step, alignment.
I have to agree with Vlad a tiny bit as in that I think this is mainly a way (for you) to understand how RC works and what all the settings mean. That doesn’t mean that it’s unneccessary, on the contrary, it may be just what many people need to know - if they have the patience to read through it all (which might be difficult for the snapchat-generation nowadays…
